• A wireless client is a radio connected to a user’s computer.

• An access point is a radio with a wired connection to a network, which can

connect with numerous wireless clients and let them access the network.

• A bridge is a radio that relays communications between access points and

wireless clients, extending a network’s range.

Traditionally, a wireless network operates in one of two ways.

• An “infrastructure” type of network has one or more access points and one or

more wireless clients. The wireless clients connect to the access points.

• An “ad-hoc” type of network is one in which there is no access point. Wireless

clients connect to one another in order to exchange information.

The following figure provides an example of a wireless network.

Figure 36 Example of a Wireless Network

The wireless network is the part in the blue circle. In this wireless network,

devices A and B use the access point (AP) to interact with the other devices (such

as the printer) or with the Internet. Your ZyXEL Device is the AP.

Every wireless network must follow these basic guidelines.

• Every device in the same wireless network must use the same SSID.

The SSID is the name of the wireless network. It stands for Service Set

IDentifier.
